Struct TreeSitterRegistry 

pub struct TreeSitterRegistry {
    pub extension_map: TreeSitterExtensionMap,
    pub languages: TreeSitterConfigMap,
}

Combined Tree-sitter registry used by the UI layer and FFI boundary.

Fields

extension_map: TreeSitterExtensionMap

Mapping from extension → language id.

languages: TreeSitterConfigMap

Mapping from language id → file-based config.

Implementations

impl TreeSitterRegistry

pub fn from_json_str(json: &str) -> Result<Self, TreeSitterRegistryError>

Parse a schema-versioned Tree-sitter registry JSON string.

The registry supports:

• absolute paths
• or relative paths resolved against root_dir

pub fn language_id_for_path<'a>(&'a self, path: &Path) -> Option<&'a str>

Return the configured language id for a file path, based on its extension.

pub fn scan_language_configs( root_dir: &Path, ) -> Result<TreeSitterConfigMap, TreeSitterRegistryError>

Scan a treesitter/ root directory and return a language_id -> config map.

This is useful for hosts that follow the conventional on-disk layout:

treesitter/
  rust/
    language.wasm
    highlights.scm

Trait Implementations

impl Clone for TreeSitterRegistry

fn clone(&self) -> TreeSitterRegistry

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TreeSitterRegistry

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TreeSitterRegistry

fn default() -> TreeSitterRegistry

Returns the “default value” for a type.

impl Eq for TreeSitterRegistry

impl PartialEq for TreeSitterRegistry

fn eq(&self, other: &TreeSitterRegistry) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
